I use a Moss 500 12ga 24" rifled barrel cantilever scope (Simmons 4x32) with
Remington's 2-3/4" Premier Core-Lokt Bonded 12 guage slug.
This is a extremely flat shooting slug that is good out to 200yds.
MOSS, 500 FULLY RIFLED BARREL WITH CANTALIVER SCOPE MOUNT and 2 3/4 remington Buck Hammer ($7 a box) Love the copper solid but way to exspensive anymore and the Buck Hammer has proved its self to me this season
I can put all 5 shots with the buck hammer back inside the box at 100 yards
I have a couple 54 flintlocks and a 50 flinter but for the past several years this has been my go to gun for deer season
It started it's life when I found a custom barrel maker in New Hampshire selling the barrel on ebay. Not sure what it was meant for but imagine a BP Cartridge gun of some sort. He stated in the listing that it was a stainless steel barrel, in 50 cal, 1-20 twist and 1 and 1/8 " in diameter, but that it had a gald spot on the rifling on one end. I got it for 12 bucks took it to an old gunsmith friend who also happens to be a Master machinist and he planed it to tapered octagon, 1 and 1/8 " at the breach and 3/4 " at the muzzle. We breached it at the end with the galling. Got to love the stainless. Shoots a 385 grain hard lead bullet. I hammered out the buttplate and had the wood from a tree that blew over, traded for the lock. Anyway I have way less than 50 bucks in her.
